摘要
The environmental protection has become one of the factors that affect and restrict the development of human society. With the continuous development of industry and the rapid increase of urban population, a large number of industrial and domestic sewage discharges into rivers and lakes without treatment, so that the environment and the application of water are seriously polluted. In this paper, the principle and characteristics of PLC(PLC is the abbreviation of Programmable Logic Controller)are introduced;the process of PLC sewage treatment is expounded, and the application of PLC in sewage treatment is described.
